SCs def have more value than their unsooted cousins. But I don't play them to hit a flush or straight. It's a nice bonus, esp when you can hit the straight vs someone who can't fold TPTK or 2 pr. But you gotta use them to steal pots as well from CO or Bu (esp the lower ones) as you're not gonna hit a made hand that's strong enough to SD enuff times to make it +EV.
